Eliezer is arguing for the hearer being physical, i.e. affecting the world. Ditch the meta.
Whatever qualia are, they happen in the brain, and are physical. Presumably in the future you can connect them to particular measurable brain activity because people can report them.
In Zombies! Zombies? Eliezer mentions that one aspect of consciousness is that it can causally affect the real world, e.g. cause you to say "I feel conscious right now", or result in me typing out these words.
Even if a generally accepted mechanism of consciousness has not been found yet are there any tentative explanations for this "can change world" property? Googling around I was unable to find anything (although Zombies are certainly popular).
I had an idea of how this might work, but just wanted to see if it was worth the effort of writing.
